Application October 27, 1936, Serial No. 107,845 In Canada April 7, 1936 4 Claims.

This invention relates to the erection of protective structures around concrete, masonry, or other work such, for example, as piles, piers and docks. The object is to provide an economical s and easily erected structure which will give ample protection against damage due to frost, ice action, or abrasive or erosive action of any kind.

According to this invention a skeleton frame, including vertical corner angles7 is first erected around the structure to be protected and the sides of the frame then closed oil by boards or other sheeting members placed one on top of the other so that the ends of the boards or sheeting members of each side are held in place by the corner angles and also by interlocking engagement with the sheeting members of the adjacent side or sides.

Proceeding now to a more detailed description reference will be had to the accompanying drawings, in which Fig. l is a View, in side elevation, of the protective structure as applied to a single concrete pile.

Fig. 2 is a horizontal section taken substantially along the line 2 2 oi Fig. l.

Fig. 3 is a sectional View along the line 3-3 of Fig. l.

Fig. 4 is a sectional view along the line 4-4 of Fig. 2.

Fig. 5 is a view similar to Fig. 2 but showing a modification of the invention as applied to a pile cluster.

In the construction shown in Figs. l to 4 inclusive, 5 designates a concrete pile and 6 the protective structure which is erected around the pile in accordance with the present invention.

As here shown the protective structure comprises vertical corner angles I which are spaced from the corners of the pile by topand bottom timber frames generally indicated at il and 9, Each of these timber frames consists of four timbers I0, I l, I2 and I3 assembled in rectangular formation with their inner edges engaging adjacent sides of the pile as clearly shown in Figs. 45 3 and 4. The ends of the timbers Ill and Il are reduced in thickness and interlock with the similarly reduced ends of the timbers I2 and I3, as indicated at ifi in Figs. 1 and 4.

At each side of the pile the space between the corner angles l is closed off by a series of boards or sheeting members I5 placed one upon the other in edge to edge relation, with their end portions received within the corner angles as clearly shown in Fig. 2. In order to prevent in- Ward displacement thereof the boards or sheeting members I5 at each side of the protective structure are interlocked, as indicated at I'l, with the boards or sheeting members oi the two adjacent sides. The top timber frame t rests directly on the uppermost boards or sheeting members I5 and serves to hold said members against vertical displacement.

The entire protective structure is secured in place around the pile by suitable fastening bolts indicated at I8 and I9. As clearly shown in Fig. 3, these bolts serve to clamp the corner angles 'I against the corner portions oi the timber frames 8 and 9 which, in turn, may be directly fastened to the pile in any desired manner.

The space between the pile and the boards or sheeting members I5 of the protective structure may be left void or may be filled with gunite or any other suitable material. In the present instance I have shown a lling 2t oi gunite provided with metal reinforcement generally indicated at 2 I.

The protective structure described in the foregoing is erected by rst applying the lower timber frame 9 and the corner angles 'I. rIhe boards or sheeting I5 are then arranged in place and s ecured against Vertical displacement by the upper timber frame 8. The corner angles 'I may be secured to the timber frames 8 and 9 in any suitable manner, in addition to being held in place by the bolts I8 andy I9. 30

Fig. 5 illustrates the manner in which the protective structure may be erected around an existing pile cluster. In this case corner ller pieces 22 may be employed at the corners 23 instead of metal corner angles. It will also be noted that certain of the fastening bolts I8 and Iii employed for holding the protective structure in place are anchored either in the piles or in portions of the gunite filling which is placed in the spaces between the individual piles and between the piles and the protective structure. Aside from these differences and the necessary variation in shape the protective structure shown in Fig. 5 is essentially the same as that shown in the preceding figures.

Having thus described my invention, what I claim is:-

1. A protective enclosure for piles, piers, docks and similar structures comprising vertically spaced top and bottom frame members mounted on the structure to be protected, vertically extending angle irons engaged with corner portions of said frame members, said angle irons being spaced from said structure, and superposed sheeting members extending between the angle irons at each side of said structure, the sheeting members at each side of the protected structure being held against vertical displacement between the top and bottom frame members and being held against horizontal displacement by said angle irons and by interlocking engagement with the sheeting members at the adjacent sides of said structure.

2. A protective enclosure for piles, piers, docks and similar structures comprising vertically spaced top and bottom frame members mounted directly on the structure to be protected, vertical angle irons clamped to corner portions of said frame members, superposed sheeting members extending between the angle irons at each side of the protected structure, the ends of the sheeting members at each side of said structure being positioned inside the adjacent flanges of the angle irons and being interlocked with the ends of the sheeting members at adjacent sides of said structure, the interlocking connection between the sheeting members being such as to prevent inward displacement thereof toward the protected structure.

3. A protective enclosure for piles, piers, docks and similar structures comprising vertically spaced top and bottom. frames mounted directly on the protected structure, vertical angle irons clamped to corner portions of said frames, superposed side boards extending between the angle irons at each side of said structure, the side boards at each side of said structure being spaced therefrom and being held against vertical displacement bythe top and bottom frame members, and suitable filling material disposed in the space reserved between the protected structure and the angle irons and side boards of the protective enclosure.

4. A protective enclosure for piles, piers, docks and similar structures comprising vertically spaced top and bottom frame members mounted directly on the protected structure, vertical angle irons engaging corner portions of said frame members, each angle iron being fastened to the two adjacent angle irons by clamping bolts serving to yclamp the angle irons firmly against the corner portions of the frame members and sheeting members extending between the angle irons at each side of the protected structure to form vside Walls extending from the bottom to the top frame member to complete the enclosure.
